Problems solved by technology
[0002] At present, the most advanced surface sizing liquid preparation system has the function of continuous starch cooking, but the system has high requirements for control and a large investment. Retiring old systems is also a waste
Once the traditional intermittent batch glue cooking system cooks glue in batches, the glue concentration will be relatively fixed within a certain range. When it is necessary to increase or decrease the glue concentration, it will take a long time before cooking, which will bring problems to the paper production. Great inconvenience or even hidden danger

Embodiment Construction
[0027] Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail:
[0028] Such as figure 1 As shown, a dual-concentration surface sizing control system for papermaking according to the present invention includes a first liquid storage tank 1 and a second liquid storage tank 2 for preparing the glue solution and a glue solution for adjusting the concentration of the glue solution Mixer 3, the first liquid storage tank 1 and the second liquid storage tank 2 are respectively connected to the glue liquid mixer 3 through pipelines, and the discharge end of the glue liquid mixer 3 is connected to the glue sizing process of the glue sizing operation. The weir pool, the weir pool is formed by two contacting cylindrical surface sizing rollers (commonly used with a diameter of 1-1.5m), and its volume is related to the length and diameter of the surface sizing rollers. Paper machine, the volume of the weir pool is generally 0.4-0.6m ...

The invention discloses a papermaking double-concentration surface sizing control system which comprises a first liquid storage tank and a second liquid storage tank for preparing size liquid and a size liquid mixer for adjusting the concentration of the size liquid, wherein the first liquid storage tank and the second liquid storage tank are connected with the size liquid mixer through a pipeline respectively; the sizing liquid mixer is connected with a sizing pond for sizing operation. The invention also discloses a papermaking moisture and transverse ring crush index control method. The papermaking double-concentration surface sizing control system and papermaking moisture and transverse ring crush index control method thereof disclosed by the invention are applicable to the field of papermaking production control. The invention is aimed at providing a low-cost papermaking double-concentration surface sizing control system which has high practicability and is simple and easy to implement and a simple and efficient papermaking moisture and transverse ring crush index control method with wide applicability.
Description
【Technical field】 [0001] The invention relates to a dual-concentration surface sizing control system for papermaking and a control method for papermaking moisture and transverse ring pressure index, which are suitable for the field of papermaking production control. 【Background technique】 [0002] At present, the most advanced surface sizing liquid preparation system has the function of continuous starch cooking, but the system has high requirements for control and a large investment. Retiring old systems is also a waste. Once the traditional intermittent batch glue cooking system cooks glue in batches, the glue concentration will be relatively fixed within a certain range. When it is necessary to increase or decrease the glue concentration, it will take a long time before cooking, which will bring problems to the paper production. Great inconvenience and even hidden dangers. The reason is related to the continuous production control of papermaking. The biggest impact is t...
